3.1.5d All electronic voting machines shall provide a minimum font size of 3.0 mm (measured as the height of a capital letter) for all text.

TA 315d-1 FOR all text content on a visual electronic display, the measured height of all capital letters in that text content SHALL be at least 3.0 mm.

3.1.5e All voting machines using paper ballots should make provisions for voters with poor reading vision.

TA 315e-1 IF a voting machine uses paper ballots, THEN the voting machine SHOULD provide voters with poor reading vision a means to read the ballot.

TA 315e-2 IF a voting machine uses paper ballots, THEN the voting machine MAY provide paper ballots in at least two font size ranges, 3.0mm to 4.0mm inclusive and 6.3mm to 9.0 mm inclusive, to allow voters with poor reading vision to read the ballots.

TA 315e-3 IF a voting machine uses paper ballots, THEN the voting machine MAY provide a magnifying device to allow voters with poor vision a means to read the ballots.

TA 315f-1 A visual voting system's display MAY use high luminosity contrast in order to be able to recognize visual features.

TA 315f-2 Color-coded graphics in a visual voting system's display MAY use shape to improve the voter's ability to distinguish features.

TA 315f-3 A visual voting system SHOULD present ordinary information to the voter in black text on a white background.

TA 315f-4 A visual voting system SHOULD reserve the use of color for special cases (including but not limited to warnings or alerts).

TA 315f-5 A visual voting system SHOULD NOT present information to the voter in the form of colored text on a colored background.

TA 315f-6 FOR all information provided to the voter by a visual voting system, no other than the following four possibilities SHOULD be allowed: (i) white text and colored background, (ii) colored text and white background, (iii) black text and colored background, or (iv) colored text and black background).

TA 315f-7 FOR a voting system, if any text is colored other than black or white, THEN all of the following SHALL be true: (i) the background SHOULD be black or white, (ii) the text SHOULD be presented in a bold font (minimum 0.6 mm stroke width), (iii) IF the background is black, THEN the text color SHALL be yellow or light cyan, and (iv) IF the background is white, THEN the text color SHOULD be dark enough to maintain a 10:1 contrast ratio.

TA 315f-8 IF the background is colored other than black or white on a visual voting system, THEN the following SHOULD be true of the presentation: (i) the text color SHALL be black, and (ii) the background color SHALL be yellow or light cyan.

3.1.5g Color coding shall not be used as the sole means of conveying information, indicating an action, prompting a response, or distinguishing a visual element.

TA 315g-1 A visual voting system SHALL use a non-color mode, in tandem with any implemented color coding, to convey all information to a voter using that system.

TA 315g-2 A visual voting system MAY use shapes (such as red enclosed in an octagon shape), in tandem with any implemented color coding, to convey information to a voter using that system.

TA 315g-3 A visual voting system MAY use text styles (such as italic), in tandem with any implemented color coding, to convey information to a voter using that system.

TA 315g-4 A visual voting system MAY use any other non-color method, in tandem with any implemented color coding, to convey information to a voter using that system.

TA 315g-5 FOR a visual voting system, NO icons or controls SHALL be distinguishable only by color to a voter using that system.

3.1.5h All text intended for the voter should be presented in a sans serif font.

TA 315h-1 FOR a voting system, all text presented to a voter using that system SHOULD use a sans-serif font.

3.1.5i The minimum figure-to-ground ambient contrast ratio for all text and information graphics (including icons) intended for the voter shall be 3:1.
